Total time and efficient time management: in search of optimal learning and retention via study-test-rest...

Bugelski's total time hypothesis (TTH) assumes that a constant time X is needed to learn Y regardless of how time X is programmed, with no possibility of optimization. Izawa's study-test-rest (STR) hypothesis assumes that optimization in learning and retention is possible. Examined were the effects of varied study (S) and test (T) presentation programs on learning and retention, with total time held constant. Participants learned a list of 12 paired associates under three presentation program types. In S + T list repetitions, each pair was presented once per S cycle and tested once per T cycle; both S and T were repeated in list form. In S + T item repetitions, each pair was repeated 1-6 times before the next pair in the list was presented on both S and T cycles. For S/T alternations, the entire list of pairs was studied and then each pair was tested, with S and T cycles alternating. Under each program type, there were four presentation rates. Item repetition led to more learning than list repetition when the presentation rate was very fast. Learning and retention were greatest with the intermediate S/T alternation program. These findings supported Izawa's STR hypothesis but strongly contradicted TTH.
